The spirit of QRP

63 Comments

Here we are, on the morning of Christmas Eve, and I find this quote from Teddy Roosevelt  floating around in my head:

“Do what you can, with what you have, where you are.”

                                    –– Teddy Roosevelt

Perhaps I’m thinking about these words because they sort of fly in the face of all of the consumerism that often surrounds the holiday season…?

Well, I’m not sure of the reason.  What I do know is, I feel like this quote speaks to me as a QRPer. Part of the appeal of low-power operations is making do with less. With just a faint breath of power, I can reach across the globe to connect with others, and have just as much fun doing it as the guy with the tall backyard tower.  Yes, I have to admit, there’s a certain satisfaction in that.

You might not know this, reading QRPer.com, where we often talk gear, discussing its various shortcomings and merits, but I’m actually a fan of simplicity.  Outside of the world of radios and packs––and even in it, to a degree!––I try not to own too many things.

In my little QRP world I feel incredibly fortunate to be able to beta test, review, and evaluate a wide variety of radios and gear. Since I do purchase almost all of my review radios––except for the few that are loaned to me––I’ve accumulated a lot of them over time. I know I can sell the ones I don’t often use, and I frequently do, but it’s fun to take them out for a spin now and again; you may notice that I rotate them out regularly.

Yet because of this, I do worry that people read my posts (and those of others in the ham community) and reflect with despair along these lines: “I can’t activate in the field…I need a lot of new expensive gear to do that!”

But this couldn’t be further from the truth.

For four years, when I lived in Germany and the UK, I only owned one radio–a Yaesu FT-817. And, know what?  I had so much fun with that single radio and a limited number of home-brew antennas.

To which I might add, this past year, some of my most memorable activations have been with radios I purchased for under $200:

I could easily activate all of the parks and summits I wish, only using one of these little radios, coupled with a key, a home-brew wire antenna, and a battery.  That’s it~!

So, you really don’t need a lot of gear to enjoy field radio.  This is true especially if you’re a CW operator.  But even just starting out, you really can have fun with a simple field kit.

Even if you’re new to ham radio, don’t wait to hit the field until you’ve assembled the “perfect” or the largest, finest field radio kit. Instead, take Teddy Roosevelt’s advice,  and just do what you can with what you have…right where you are.  

Here’s wishing everyone

A Very Happy Holiday Season!

Pairing the Elecraft KX2 and AX1 with a little QRP Coffee for some proper portable POTA fun!

16 Comments

Driving home on Thursday, December 8, 2022, I popped by Food Matters in Morganton, NC and grabbed one of their amazing curried chicken salad wraps.

I sat in the car and listened to a podcast as I ate a late-ish lunch. I looked at my watch and sorted out what time I needed to be back at my home in the mountains. After a little mental math, I realized I had about 90 minutes to fit in a little radio fun.

Where to go on a rainy day?

Tuttle Educational State Forest (K-4861)

Since it was a Thursday and I knew Tuttle would be open, it was really a no-brainer. Tuttle is only an 8 minute drive from the parking lot at Food Matters, so I made my way to Playmore Beach Road!

En route, I made a mental inventory of what radios and antennas I had packed in the car. I knew I had my KX2 and although its internal battery had already powered me through three or four activations already, I knew there’d be enough charge for one or two more.

Also, since it was raining, I thought it would be the perfect day to set up under Tuttle’s excellent picnic shelter.

As for an antenna, I remembered putting the AX1 in my antenna box, so why not pair the two and operate in the dry?

Coffee Time

Funny, but after I started recording the activation video (below), I convinced myself that I needed to make some coffee. I pulled out my field coffee kit and set it up for a quick brew.

The park had completely shut off all water fountains and closed the rest room area, so there was no place to get fresh water. Fortunately, I had *just* enough water left in my water bottle after lunch. Almost the perfect amount for a cup of coffee but no more.

This wasn’t a planned cuppa’ so I used one of my last Starbucks Via coffee packs. Had I planned this in advance, I would have ground some beans at home and made a pour-over coffee.

That’s okay, though. The Starbucks packs are better than no coffee at all.

Jim’s Elecraft KX2 leg mount

12 Comments

Many thanks to Jim (WU3K) who writes:

Hi Thomas,

I recently came up with a new way (for me) to hold the KX2 when I am out in the field.

The set-up utilizes the Side KX KX2 mount and the RAM Body Mount for Legs.

This set up does a pretty good job for me.

73,

Jim

This is absolutely genius, Jim! Besides the leg mount looking like a excellent solution, the Side KX mount could then be used for other mounting locations either at home or mobile!

Thank you for sharing!

Testing a new QCX-Mini Field Kit built in an Evergreen 56 Watertight case

11 Comments

In early November, I happened up a new waterproof case called the Evergreen 56. As with Pelican cases, it’s waterproof and also made in the USA. Like Nanuk cases (that are also waterproof and made in Canada) Evergreen cases have a built-in locking mechanism to keep the latch from accidentally opening during transport.

I thought the price for the Evergreen 56 at $28 US was fair and in-line with the Pelican 1060 and Nanuk 903 which are similar in size. I grabbed one made of a clear material with one radio in mind: my QCX-Mini!

There are a number of color options available for this Evergreen case, but I like the clear polycarbonate one because it makes it so much easier to see what’s inside (for a quick gear check) but also to confirm that no one part of the kit is being pressed too hard inside the case after the lid is sealed.

After receiving the Evergreen 56, I was very pleased with the quality–again, on par with what I would expect from Pelican or Nanuk.  It is incredibly solid and the seal is watertight.  The Twist Lock Latch (see above) is easy to operate and the case comes with two “keys” for adjusting the inner lock.

The Evergreen case has a soft egg crate-like rubber boot interior as opposed to the pick foam material you’d typically find in a water tight case. The case also has a hammock-like rubbery webbing on the inside of the lid that can be used to organize smaller contents (I knew instantly I’d use this to hold the antenna!).

The QCX-Mini fits in the Evergreen case perfectly–this was no surprise–but I was eager to see if my other station components could also fit. Note that I didn’t buy anything specifically to be used in this case; I used components I already owned. I could minimize the contents even further if I used a smaller battery, antenna, and key.  Here are the components of the first version of the QCX-Mini Field Kit: Continue reading Testing a new QCX-Mini Field Kit built in an Evergreen 56 Watertight case →

Rich’s easy-to-build and incredibly affordable Field Clip Board V 1.0

9 Comments

Many thanks to Rich (KQ9L) who writes:

Hello Thomas,

I’ve attached couple pictures of V1.0 of my field clip board. I’ve been searching for the perfect clipboard to use in the field. The main requirements of the design include: lightweight, low cost and the flexibility to allow a comfortable operating position while securely holding a radio.

What I came up with is a based on an inexpensive fiber board clip board:

I chose to set it up somewhat unconventionally and designed it to use the clipboard “upside down”.  Setting it up this way provided ample space at the top to mount the radio while still providing room to attach a metal pad mounting point for paddles.

The radio is held securely in place with craft 3mm elastic bands. The bands were made with metal “toggles” so I can easily add more holes to the clipboard to accommodate varying rigs.

The metal pad is just a stick-on metal plate purchased from Amazon. I plan to add a leg strap in the future and will do so once I’m sure no other major modifications need to me made.

I’m pretty happy with the way the clipboard came out and would appreciate any comments or suggestions!

This is brilliant, Rich! I love both how affordable this board is and how easy it is to build. Having the clip at the bottom of the board is a fantastic way to secure your logging notebook as well. 

Thank you for sharing!

Charles’ simple solution to protect the MC-750 ground spike tip

4 Comments

Many thanks to Charles (KW6G) who writes:

Thomas:

I purchased an MC-750 from DXE last week…It arrived Monday….Great antenna; very nice workmanship….I have not yet deployed it, but that will be in the near future….

After reading your emails/posts and viewing the videos, I got to thinking…The real oversight in this antenna design is the fact that the manufacturer has provided no protection for the tip of the ground spike….I can see where it would not be long until it worked its way through one of the ends of the carrying pouch…

So with this in mind, I went off to the hardware store where I found a 3/8″ ID X 1 inch long nylon spacer which fit over the end of the spike perfectly — problem solved for all of 58 cents…

Here are a couple photos:

What a great, affordable solution! Thank you for sharing this, Charles!

Testing a new Tufteln knee board and antenna during this beautiful SOTA activation on Mount Mitchell

13 Comments

On the morning of November 4th, I woke up with one thought on my mind: “I need to activate Mount Mitchell before it’s too late!”

It’s not like Mount Mitchell was going to disappear, but I knew I was already on borrowed time since the long section of the Blue Ridge Parkway I use to drive to Mount Mitchell from Asheville typically closes in the early part of November for weeks at a time. The park itself will close to guests too–in fact, last year, it closed its gates as I drove out of the park! There are often other roads open to Mitchell in the winter, but they’re very much out of the way for me and frankly, weather can shift and the park close at the drop of a hat.

As the crow flies, Mount Mitchell is actually very close to my QTH. If I wanted, I could hike there directly from my home. I’ve yet to do this, however, because with the 3,000′ elevation change and the anything-but-direct trails that skirt the Asheville watershed, I’d need a full day or more to hike it one way. I will for sure do this sometime, but only when I can pack appropriately and reserve a campsite.

Morning drive

As soon as I surfaced that morning, I check the weather map. I noticed that the temp at Mount Mitchell was actually slightly higher than at my QTH. I looked out the kitchen window and could see fog in the valley. This meant one thing: inversion!

When we have inversion, the cold air is pushed down into the valley and warmer air can be found at higher elevations. The flip opposite of what you’d typically expect.

I ate a quick bite, grabbed come coffee, and hit the road.

As I drove past Warren Wilson College’s farm, it was absolutely gorgeous. I had to stop and take a photo or two [click images to enlarge].

The drive up to Mount Mitchell on the BRP was ideal: clear skies and quite warm!

In fact, I felt like I really struck it lucky that day. I didn’t even need a heavy jacket or gloves. Continue reading Testing a new Tufteln knee board and antenna during this beautiful SOTA activation on Mount Mitchell →

Pairing the Elecraft KX2 and Chelegance MC-750 for a quick QRP POTA activation

16 Comments

After a fun “discovery” activation with the TEN-TEN R4020 on the morning of November 12, 2022–click here to check out that report and video–I realized I had just enough time to squeeze in another activation on my way back to the QTH.

I picked Lake James State Park (K-2739) because it was the most conveniently located; only a 20 minute detour.

When I arrived, the park was very quiet even though it was a Saturday no doubt because the ground was still saturated after the two days of rains we received from the remnants of Hurricane Nicole.

I grabbed my radio gear: the Elecraft KX2 and the new MC-750 vertical antenna sent to me (at no charge) by Jesse at Chelegance. This was only the second time I’d used the antenna–the first time was with the X5105.

I knew the MC-750 would be quick to set up and that was a good thing because I only had a max of about 45 minutes for the entire activation including set-up and take-down.

I walked down to a picnic table by the lake and deployed the station.

The MC-750 took me all of three (casual) minutes to set up.

Next, I set up the Elecraft KX2 and my CW Morse Outdoor Paddle with Steel Base for one-handed picnic table operating.

Of course, I also needed to prepare a log sheet even though I planned to live log everything in the HAMRS app on my phone. Continue reading Pairing the Elecraft KX2 and Chelegance MC-750 for a quick QRP POTA activation →

A review of the LnR Precision Mountain Topper MTR-4B ultra-portable QRP transceiver

15 Comments

The following article originally appeared in the November  2022 issue of The Spectrum Monitor magazine:

A Review of the LnR Precision Mountain Topper MTR-4B V2

by Thomas (K4SWL)

I confess, there is something that I’ve come to believe is almost a rite of passage in the SOTA (Summits On The Air) community. And, no, I’m not talking about activating an All Time New One (ATNO) summit, or completing a particularly challenging activation on a snow-capped peak.

I’m talking about owning one of the iterations of the amazing “Mountain Topper” pocket-sized QRP CW transceivers designed by Steve Weber (KD1JV).

This little radio first caught my attention at a Four Days In May (FDIM) QRP conference over a decade ago: a ham friend in the SOTA community proudly showed me a very early version of the Mountain Topper that he built from a kit. The first thing that struck me was how impossibly small and extraordinarily lightweight it was. But when he showed me the 9-volt battery he used to power it––a power supply not only small, but convenient––I was mesmerized.

Over the years, the Mountain Topper has evolved.  There have been many models, ranging from two bands to five. To my knowledge, they’re no longer offered in kit form, but LnR Precision manufactures and tests these in North Carolina, and they’re better than ever in terms of features and performance.

At present, the MTR-4B V2––the second version of the four-band Mountain Topper––is the only model in production, and if you’re hoping to acquire one, due to supply chain issues (at time of publishing) there’s a rather long wait time. They retail new for $350 US, and frankly, the used ones I’ve seen posted in ham radio classifieds ads have been equal to, or even over, the listed price for a new rig.  Obviously, demand for these radios is much higher than supply.

So, how could it be that this minuscule QRP radio performs well enough to produce some serious DX from a remote summit…so well, in fact, that people are willing to wait in line for one?

Magic or method?

As any CW operator will tell you, the magic is in the mode. CW is such an efficacious mode that it cuts through the ether like a knife, even when conditions are less than favorable.

Obviously, pint-size radios like the Mountain Topper are QRP––low power––so designing them around such a simple mode is a very smart choice. CW transceivers are much less complex than a similar SSB transceiver, thus have less components, less mass, and are in general more affordable (when compared to those with similar receiver performance).

My comprehensive MTR-4B field kit (the MTR-4B is in the mesh pocket).

In addition, the Mountain Topper is designed with the field activator in mind:  specifically, SOTA activators, but of course, POTA (Parks On The Air), WWFF (World Wide Flora and Fauna), IOTA (Islands On The Air), or any other popular “-OTA” field activity. As a field activator in one of these programs, you are the DX. This means chasers and hunters are actively seeking your signal, and thus you are not competing with blowtorch stations to punch through a pileup.

I can also assure you that standing on a tall summit also gives you a brilliant starting point for your QRP signal. Some of the best DX I’ve ever worked has been from a summit.

So, for the average CW SOTA activator, QRP is preferred because QRO simply isn’t necessary––indeed,  in my opinion it’s a bit of an overkill. At least that’s been my experience now with my few hundred SOTA, POTA, NPOTA, SOTA, and even one Lighthouse On The Air activations.

So this brings us back to the wee Mountain Topper series and the model being reviewed here in the pages of TSM: The Mountain Topper MTR-4B. Continue reading A review of the LnR Precision Mountain Topper MTR-4B ultra-portable QRP transceiver →
